Instant kill:Press [Ctrl] + X to instantly down an enemy fighter. Note: The kill will not count towards the score.

Retain character:Quickly press [Esc] after your plane has been shot down or has crashed. Select the "End Mission" option. Your pilot will still be alive at the current score and rank, but without the points for the last mission. Note: This will not work if your pilot is killed by a direct bullet hit.
